MAMP database error

I've been developing a Drupal site locally using MAMP. For some reason when I was saving something the site became and responsive so I refereshed to no success. So out of frustation I closed the browser tried another one but now the site doesn't show up at all.

I've tried repairing the tables in phpMyAdmin but nothing has worked. All my other local sites are fine its just this specific site. Anyone know how I can fix the database?
